Question:

Have a new Mercedes Benz that has a 7 way female trailer plug in but my trailer has a 4 way male plus a 4 flat. What adapter do I need?

Hey Terry, all that you need is a 7-way to 4-way adapter like the part # HM47365 and you'd be set. This will convert the 7-way of your MB to a 4-way like your trailer needs.

Hey Terry, how did the 7-way to 4-way adapter work with your Mercedes and trailer setup? Your results could really help others trying to connect similar wiring.
